The formula of Touch of Red had an excellent consistency that was thin but not watery; it applied without streaking, but it wasn’t completely opaque after two coats–though it is certainly close. It’s only at certain angles and lighting situations where you can see the white of the nail line. It flowed easily across the nail without bubbling or pooling along the sides. I don’t have any issues with MAC’s lacquer formula as far as wear goes; I get a week of wear with minor tip wear but no chipping.
